Zusammenfassung:	In one embodiment, an anti-rotation system includes a first tubular member (110) having an extended thread and a torque shoulder, the first tubular member (110) comprising a radial recessed area, the radial recessed area located axially between the external thread and the torque shoulder of the first tubular member (110). The system may further include a second tubular member (120) comprising a radial recessed slot, the radial recessed slot located in the inner circumference of the second tubular member (120). The system may also include a pin toothed insert (130) mechanically coupled to the first tubular member (110) within the recessed area, the pin toothed insert (130) comprising a first circumferential tooth pattern facing radially outward from the first tubular member (110). The system may also include a spring loaded, radial ratchet dog (210) located within the radial recessed slot, the spring loaded radial ratchet dog (210) comprising a second circumferential tooth pattern facing radially inward from the second tubular member (120). The spring loaded radial ratchet dog (210) may be movable radially outward over the pin toothed insert (130) during coupling of the first tubular member and the second.tubular member (110, 120). Furthermore, the spring loaded radial ratchet dog (210) may engage the pin toothed insert (130) and resisting decoupling of the first tubular member and the second tubular member (110, 120).
